The Optimization Design Research on the Seismic Control of Large-span Spatial Structure

摘要

Focuses on the dynamical collapse of large-span spatial structure, this paper uses giant magnetostrictive material as the main component to design a kind of new GMM actuator, which could used in active vibration control of large-span spatial structure. The genetic algorithm has been used to optimize the position of actuators in large-span spatial structure, and the optimization of the results has been analyzed by numerical simulation. The research shows that the GMM actuator has fine actuator effectiv.
